H.W. 1.1: it is required to maintain a loading of 5 kW in a heating unit. At an initial temperature of 15 C°, a voltage of 200 V is necessary for this purpose. When the unit is settled down to a steady temperature, a voltage of 220 V is required to maintain the same loading. Estimate the final temperature of the heating element, if the resistance temperature coefficient of the heating element is 0.0006 per C° at 0 C°.

You want to buy electric energy. You can buy from company A, B, C, or D,but you must choose only one. You obtain past data on these four suppliers, and you then determinethat the prices for some of them have been quite volatile, influenced by the state of the economy(recession, stagnation, and inflation). You assess this data given in the table below. Assuming that you simply want to minimize your average costs over the long run, determine theexpected costs for all energy suppliers. Select the supplier based on minimum expected cost.
1. Incremental cost fuel cost is GHC per megawatt hour for two units in a plant are given by dF1dP1=0.1P1 + 20 dF2dP2=0.12P2 + 16 The minimum and maximum load on each unit is to be 20 MW and 125MW respectively. Determine the incremental fuel cost and the allocation loads between units for this minimum cost when loads are i) 100MW ii) 150MW . Assume both units are operating.
Incremental fuel costs in dollars per megawatthour for a plant consisting of two units are given by:dC(P)/dP = 0.0080 P1 + 8.0dC(P)/dP = 0.0096 P2 + 6.4Assume that both units are operating at all times, that total load varies from 250 to 1250 MW, and that maximum and minimum loads on each unit are to be 625MW and 100MW respectively. Find the incremental fuel cost and the allocation of load between units for the minimum cost of various total loads.Write your answers in the given format below.

A power plant produces 1000MW to supply a city 40km away. Current flows from the power plant on a single wire with resistance through the city and returns via the ground, with negligible resistance. At the power plant the voltage between wire and ground is 115 kV. Determine: (a) the current in the wire, and (b) the fraction of the power lost in transmission.
The maximum demand of a power station is 110 MW. It generates 105 x 10 units during the day. The station has three units of 40 MW and another unit of 40 MW as spare. The running hours of the unit are as follows. The first unit of 40 MW runs for 24 hours. Another unit of 40 MW runs for 14 hours. A third unit of 40 MW runs for 4 hours. So Find (1) daily load factor (2) plant capacity factor (3) utilization factor and (4) plant use factor.
